cub transmission grease/fluid specs...type not quantit

[simmonsb]

i need to please know the specs/type of transmission grease/oil/fluid for the transmission....i've found the quantity in my maintenance manual but not the type...i did find that the hydraulics uses hytran but i need the transmission type oil please

thanks i advance

My local Obi Wan Cub god tells me any 80w /90 gear oil, and about a quart or a little more will do it.

Actually the Owner's manual does spec out what should be used in the transmission as well as the finals etc.



Much later or, IH started suggesting Hy-Tran in the transmission, but since the transmission itself did not change from the square cut gears, when running Hy-Tran the transmissions are somewhat noisy. By continuing to use 90 Wt Gear Oil it tends to quieten down the noise as well as lubricate the gears better. At least that is IMHO.

thanks so much for the speedy reply...i was thinking a heavy weight oil like that...best wishes to all

thanx.bs

If you choose to use gear oil instead of Hy-Tran in the transmission, the gear oil should be rated GL-4. This oil can be a little harder to find. Most gear oils are rated GL-5, which can be hard on yellow (brass/bronze) metals. I believe the PTO pilot bushing falls into the yellow metal category. GL-5 gear oil should be ok for the final drives.

The transmission capacity is 3.5 PINTS.

The only GL-4 lube I could find was straight SAE 140. Everything on the shelf at the local farm store is GL-5.

Monograde gear oils
Monograde gear oils are designated by one number (70, 90, 140, 250, etc.). The number indicates a level of the oil viscosity at a particular temperature. The higher the grade number, the higher the oil viscosity.
Viscosity of gear oils designated with a number only without the letter “W” (SAE 80, SAE 90, SAE 140 etc.) was specified at the temperature 212°F (100°C). These gear oils are suitable for use at high ambient temperatures.
Viscosity of gear oils designated with a number followed by the letter “W” (SAE 70W, SAE 75W, SAE 80W etc.) was specified at the temperature 0°F (-18°C). The letter “W” means winter. These grades are used at low ambient temperatures.

I found GL-4 SAE 75-90 at NAPA, right out in plain sight.
